Norbert Riddle lives in the United State of Earth, where normal means following the rules, never standing out, and being exactly the same as everyone else, down to the plain gray jumpsuits he wears everyday. He's been normal his whole life, until a moment of temporary hilarity when he does a funny impression of their dictator, and gets caught. Now, Norbert's been arrested and banished to planet Zorquat Three in the Orion Nebula, where kids who defy the rules roam free in the Astronuts camp. Norbert has been taught his whole life that different is wrong, but everyone at Astronuts is crazy, creative, and insane!
